A field experiment was carried out in the spring and autumn season of 2016 in fields of Field Crops Department, Faculty of Agriculture, University of Anbar,( Abu Gharib), in soil with a clay-silty texture, to determine the effect of foliar application with three concentrations of Boron; 0, 90, 180 mg L-1, and Salicylic acid; 0, 150 and 300 mg L-1, in the productive and quality traits of two mung bean genotypes, local and Indian cultivars. The experiment was took place using Split-Split Plot arrangement in randomized complete block design, where genotypes occupied main plots while salicylic acid concentration occupied sub plot and Boron concentration in the sub-sub plot. Obtained results were summaries as follow:
The concentration of 90 mg B L-1 in the two seasons showed the highest average fertility rate in pods and seeds with 696.90 and 789.70 kg-1, and protein about 188.50 and 191.30 kg-1 respectively, Concentration of 180 mg B L-1 in the same season achieved the highest mean weight of 100 seeds and protein ratio in seeds 25.15%. Boron did not significantly affect the length of the pod in the two seasons.
The concentration of 150 mg SA L-1 in both seasons gave the highest fertility rate in the pods as 69.76 and 77.53%, and the highest average yield of the seeds with 698.4 and 760 kg-1 respectively, and recorded in the spring season the highest weight for 100 seeds, In the protein content about 185.50 kg e-1, and the concentration of 300 mg SA L-1 exceeded in the autumn season in the number of seeds by pod. The genotypes differed significantly in the studied traits except for the percentage of protein in the seeds and both seasons. The local genotype showed the highest mean number of seeds by pod and seed yield by 789.20 and 791.5 kg e -1, and protein with 210.20 and 187.30 kg-1, While the Indian genotype in both seasons showed the highest average length of pod and 100 seed weight 6.74 and 7.02 g, for the two seasons respectively. The effect of triangular interference (genotype * salicylic * boron) in the two seasons was significant in the weight of 100 seeds, seed yield, protein content and yield. The local genotype with spraying with concentrations 90 mg B + 150 mg SA L-1 achieved the highest mean yield of 988.6 and 1092.9 kg e-1 for the seasons respectively and for the protein yield in the autumn season 239.9 kg h-1 protein Indian genotype with the same treatment spray highest protein content in seeds by 29.48%.
